Misaligned plots when plotting with UnicodePlots.jl using BrailleCanvas (Take 2)

[pankgeorg]

Issue still persists for raw character output.

Raw output:

@expikr can you also paste a screenshot? Thanks!

Font for ‘raw output’ looks like SF Mono or similar - you could try a different font?

[expikr]

the "raw output" is just a plaintext codeblock, you can copy it from your browser.

The UnicodePlots are not quaranteed to work in every display. If you copy/paste the text, it will only work with some fonts, but definitely not with all

Do you use this feature from Pluto? I don't see Pluto in the screenshots.

Pluto's only promise is that it should work inside the pluto viewer. Is that what you expect and does not work?

[expikr]

Ah, I wasn't aware of it being designed only for very specific environments, perhaps I missed it but the product messaging doesn't make it immediately clear that it is not meant to be universal.

At least, the intuitive expectation at a glance would lead people to think that it's a sharable output, otherwise why would anyone want to use it over actual images?

EDIT: ahh, just realized that this isn't the repository for UnicodePlots.jl itself.

[pankgeorg]

It is sharable but you need to take extra care to select a font in your editor that supports all the Unicode characters with the same width. For issues with UnicodePlots itself, you can file an issue here.

I'm going to close this issue now, feel free to reach out if you find other things going wrong with Pluto and its plots renderer!

Thanks!

I think it's also something to do with ANSI escape sequences that Terminal emulators can handle but other text environments can't.

I think it's also something to do with ANSI escape sequences that Terminal emulators can handle but other text environments can't.

In that case, it would be helpful to write the output directly to a text file and share that, without copy/pasting. Something like:

write("output.txt", repr(MIME"text/plain"(), lineplot(...)))
